SOIL SAMPLING DEVICE AND SOIL SAMPLING METHOD
To provide a soil sampling device and a soil sampling method that can collect a soil sample with less disturbance by, for example, utilizing a Swedish weight sounding test device.SOLUTION: The soil sampling device includes an outer tube 1, an inner tube 2, a screw shaft 4, a bearing 5, a push-in base 6, a piston 7, a rib 8, and a guide 9. The screw shaft 4 is provided in the inner tube 2 so that their axes O1 are arranged coaxially. The bearing 5 is provided integrally on a rear end side of the outer tube 1 and axially supports the screw shaft 4 about the axis O1 rotatably. The push-in base 6 is provided integrally on a rear end side of the inner tube 2 and rotates the screw shaft 4 about the axis O1 normally and reversely as well as advancing and retracting in the direction of the axis O1. The piston 7 is provided by being connected to the tip of the screw shaft 4, and is arranged so as to close the opening of the inner tube 2 on the tip side in the state where the inner tube 2 is retracted. The rib 8 protrudes outside from an outer surface of the outer tube 1 and prevents the outer tube 1 from co-rotating by biting into the ground. The guide 9 guides the push-in base 6 and the inner tube 2 in the direction of the axis O1 to make them advance and retract.SELECTED DRAWING: Figure 1
【課題】スウェーデン式サウンディング試験装置を利用するなどして乱れの少ない土試料を採取することを可能にする土試料採取装置及び土試料採取方法を提供する。【解決手段】外管１と、内管２と、内管２の内部に互いの軸線Ｏ１を同軸上に配して設けられるねじ軸４と、外管１の後端側に一体に設けられ、ねじ軸４を軸線Ｏ１周りに回転可能に軸支する軸受５と、内管２の後端側に一体設けられ、ねじ軸４を軸線Ｏ１周りに正逆回転させるとともに軸線Ｏ１方向に進退する押し込み台６と、ねじ軸４の先端に接続して設けられ、内管２を退避させた状態で内管２の先端側の開口を閉塞させるように配設されるピストン７と、外管１の外面から外側に突設され、地盤に食い込んで外管１の供回りを防止するリブ８と、押し込み台６及び内管２を軸線Ｏ１方向に案内して進退させるガイド９とを備える。【選択図】図１
